Siegfried von Mittgard stands as the narrative's primary antagonist, leading a faction rooted in neo-Nazi ideologies. His objective is to seize the Dragon Orb, an artifact of dark power, enabling his ascension as the Regent of Darkness and the establishment of global dominion. This ambition explicitly invokes the legacy of historical fascist regimes, directly referencing Adolf Hitler's influence on their goals.

He commands his forces to hunt down Kujaku, a mystic opposing his plans, believing Kujaku's supernatural birthright is essential for his own path to power. The conflict reaches its climax in a decisive confrontation in Tibet, where opposing forces successfully prevent him from unleashing the Dragon Orb's destructive capabilities.
